Guitar attachment



FIG. 1 is a front elevational view of a guitar attachment embodying my new design, the rear elevational view being a mirror image thereof;

FIG. 2 is a top plan view thereof;

FIG. 3 is a left side elevational view thereof

FIG. 4 is a right elevational view thereof; and,

FIG. 5 is a top, rear, left side elevational view thereof.

The broken line shown in FIGS. 1, 3 and 4 is for illustrative purposes only and forms no part of the claimed design. The appearance of the guitar attachment, as seen from the bottom, forms no part of the claimed design. 

I claim the ornamental design for a guitar attachment, as shown and described.
